Probably at least this cycle as well, and maybe next cycle too. Memes are stuff that people do not take seriously, they are just investing for fun and since we are making some profit, people do not see any trouble investing some of their profits into something more fun. It is a "F U" method of investing for some of these people, same as gamestop was, and not really the money that means anything to them, or could even a lot for them but they are making a stance at least.
They will soon realize that they are doing it with the wrong stuff, and will stop investing but that will take a few more years at least. For the time being, they are happy investing and will keep on investing as much as they possibly could to make it happen.
Dogecoin is probably the only legitimate meme coin as it is the original one, however once scammers took a look at it and they realized that they could try to emulate its success without the need to make any claims about being innovative then their job became many times easier, and those that are investing in those coins are the same, they cannot really argue they are in it to make a stance or to get some fun, when we know it is very obvious that what they want out of their meme coin investments is to make a fortune without the need to actually learn how to trade.
